As cognitive enhancement method for prevention of dementia, coimagination method is proposed: designed group conversation whose themes are selected from recent topics for training of recent episodic memory functions, since recent episodic memory functions decline before the onset of dementia. It is known that people who are disuse particular cognitive functions have higher risk of loosing the functions. However, the participants of the conversations supported by coimagination method sometimes refer to past topics rather than recent topics. The method is required for analyzing whether the topics deal with recent or past for effective intervention, which has not been established. Purpose of this study is to propose method for analyzing the temporal characteristics of the topics during conversation. Mental time travel, or chronesthesia, is the ability to...

To prevent dementia by reducing the cognitive factors, the authors of this chapter have developed the coimagination method to activate three cognitive functions that decline at an early stage of mild cognitive impairment (MCI): episodic memory, division of attention, and planning function. The coimagination method supports interactive conversation through expressing feelings about images according to a theme. Allocated time periods and turns for each participant are predetermined so that all participants play the roles of both speaker and listener. Measuring the interactivity of conversation qualitatively and quantitatively has been quite difficult, but conversation interactivity may indicate the intensity of cognitive activities. This paper proposes the conversation interactivity measuring method (CIMM) to measure the intensity of cognitive activities employed during conversation using the coimagination ...

A spread of the above mentioned mental health problems in aging societies is causing a significant medical and economic burden in many countries around the world. According to a recent World Health Organization (WHO) report, it is approximated that currently, worldwide, about 47 million people live with a dementia spectrum of neurocognitive disorders. This number is expected to triple by 2050, which calls for possible application of AI-based technologies to support an early screening for preventive interventions and a subsequent mental wellbeing monitoring as well as maintenance with socalled digital-pharma or beyond a pill therapeutical approaches. This paper discusses our attempt and preliminary results of brainwave (EEG) techniques to develop digital biomarkers for dementia progress detection and monitoring. We present an information geometry-based classification approach for automatic EEGderived event related responses (ERPs) discrimination of low versus high task-load auditory or tactile stimuli recognition, of which amplitude and latency variabilities are similar to those in dementia. The discussed approach is a step forward to develop AI, and especially machine learning (ML) approaches, for the subsequent application to mild-cognitive impairment (MCI) and AD diagnostics.

In this paper, we propose method for analyzing neural information through motion measurement. The method is on the bases of the anatomy and physiology of somatic and spinal nervous system. Muscles are classified by the innervated nerves originate from the spinal cord. The somatotopic organization inside the ventral horn of the spinal cord is utilized for topological structure of the spinal neural information. Time series of images which represent distribution of somatic information inside the spinal cord were successfully obtained through measurement and computation for sword swinging 'kesagiri' motion. The coordination of the motion at spinal level was analyzed. The proposed method provides fundamental for motor learning support system.
